Preview: Rafael Nadal resumes his quest for a record-breaking seventh French Open crown when he takes on Argentine Eduardo Schwank on Saturday. Currently ranked at 192, Schwank will be making just his second appearance in the last 32 of a major. And, with Nadal utterly untroubled thus far at Roland Garros, the Spaniard should enjoy similarly smooth progress in his third-round encounter.

Things may not be quite as straight-forward for fourth seed Andy Murray. Just two days ago Murray appeared on the verge of withdrawing from the tournament as he stared down a set and a break deficit to Jarkko Nieminen, with a back injury that meant he could barely put any weight on his left leg.

But miraculously Murray hung around long enough for the back to improve sufficiently to allow him to pull off a dramatic four-set victory. With the Scot claiming that the latest back complaint is unrelated to the one that has troubled him throughout the clay-court season, there is hope of a recovery in time for Saturday's encounter with Santiago Giraldo. And if he is fit then Murray should not be unduly tested against a man he beat comfortably in Barcelona just over a month ago.

But on a surface that tests fitness and endurance more than any other and also happens to be Murray's least favorite, there must be severe doubts as to how long he can keep battling on.

Another man experiencing physical distress in round two was Richard Gasquet, who vomited on Court Suzanne Lenglen after one particularly grueling point against Grigor Dimitrov. The talented 17th seed will be hoping for greater intestinal fortitude when he takes on inspiring veteran Tommy Haas in round three.

Featuring two of the best one-handed backhands in the game, it has the potential to be an eye-pleasing and intriguing matchup.

The women's draw is highlighted on Saturday by Maria Sharapova's contest with 28th seed Peng Shuai. Sharapova has been in dominant form in her first two rounds, surrendering just two games, and looks the player to beat this year at Roland Garros.

Having won the last two meetings between the pair last year and with Peng not having a single victory on the clay coming into Paris, Sharapova should comfortably progress once more.
